Those skilled in the art can reasonably determine the specific meanings of the above terms in the present application in combination with the specific content of the technical solution.
[0034] Refer to Figure 1 and Figure 3 , the embodiment of the present application provides an electric rocking seat, and the electric rocking seat includes a seat body 200 and an electric rocking frame 100.
[0035] The electric rocking seat further includes a seat body 200. The seat body 200 is installed on the electric rocking frame 100, and the electric rocking frame 100 can drive the seat body 200 to swing reciprocally to meet people's rocking needs.
[0036] As Figures 3 to 6 shown, the embodiment of the present application provides an electric rocking frame 100. The electric rocking frame 100 includes a rotating mechanism, a first mounting member 120, and a driving mechanism. Specifically, the seat body 200 is installed on the first mounting member 120.
[0037] The rotating mechanism includes a first transmission member 140, which has a docking end 141. The docking end 141 is connected to the first transmission member 140 by electromagnetic attraction, that is, when the electromagnetic force between the docking end 141 and the first transmission member 140 disappears, the docking end 141 and the first transmission member 140 are in a disconnected state.
[0038] The first mounting member 120 is disposed on the electric swing frame 100 , wherein the first mounting member 120 and the first transmission member 140 are configured to rotate synchronously around the same rotation center line.
[0039] The driving mechanism is engaged with the butt end 141 for driving the butt end 141 to rotate back and forth, so that the first mounting member 120 can swing back and forth.
[0040] Compared with the previous swinging mode of crank rocker plus four-link, the present application improves the transmission mode of the driving structure and adopts the meshing transmission mode for transmission. When the first mounting member 120 needs to be driven to swing back and forth by the driving mechanism, the first transmission member 140 is connected to the docking end 141 by electromagnetic attraction. The meshing transmission mode enables the first mounting member 120 to maintain a uniform swinging angular velocity during the swinging process, effectively reducing the sense of frustration during the reciprocating swinging process.
[0041] When the first mounting member 120 does not need to be driven to swing back and forth by the driving mechanism, the connection between the first transmission member 140 and the docking end 141 is disconnected, the first transmission member 140 can be freed from the rotation restriction of the driving mechanism, and the first mounting member 120 can be manually swung for swing adjustment.
[0042] In some specific embodiments, the rotating mechanism further includes a rotating shaft 161 , the first transmission member 140 is fixed to the rotating shaft 161 , and the first transmission member 140 can provide an electromagnetic force, and the electromagnetic force acts on the docking end 141 along the axial direction of the rotating shaft 161 .
[0043] The docking end 141 is rotatably disposed on the rotating shaft 161 via a bearing, so as to facilitate subsequent electromagnetic attraction and connection between the docking end 141 and the first transmission member 140 .
[0044] Among them, the first transmission member 140 can generate electromagnetic force when powered on, so that the docking end 141 is connected to the first transmission member 140 along the axial direction of the rotating shaft 161, so that the torque transmitted to the docking end 141 by the driving mechanism can act on the first transmission member 140. Since the first transmission member 140 can rotate synchronously with the first mounting member 120, when the docking end 141 rotates back and forth under the action of the driving mechanism, the first mounting member 120 can also follow and swing back and forth.
[0045] When the first transmission member 140 is in the energized state, due to the self-locking function of the driving structure, it is impossible to swing the first mounting member 120 by any means. When the first transmission member 140 is in the non-energized state, the connection between the first transmission member 140 and the docking end 141 is disconnected, and the self-locking function of the driving structure does not act on the first transmission member 140, so the first mounting member 120 can be freely rotated.
[0046] In the embodiment of the present application, the first transmission member 140 is selected as an electromagnetic clutch.
[0047] In some embodiments, such as Figure 5 and Figure 6 As shown, the first mounting member 120 includes a first connecting member 124 and a second connecting member 123. The first connecting member 124 is connected to the first transmission member 140, and the second connecting member 123 is connected to the rotating shaft 161. The first connecting member 124 and the second connecting member 123 are spaced apart. By the first connecting member 124 and the second connecting member 123, the entire first mounting member 120 is supported. While not occupying too much design space, the supporting structure formed by the first connecting member 124 and the second connecting member 123 supports a larger range of the first mounting member 120. Because the torque force that can be borne during the swinging process is also greater, the overall structure is more stable. And the first connecting member 124 is arranged on the first transmission member 140, which can make the rotation more synchronous and avoid the delay of the swinging action.
[0048] In an embodiment of the present application, the rotating shaft 161 is arranged in the horizontal direction. The first transmission member 140 is sleeved on the rotating shaft 161, and the first transmission member 140 is fixed to the rotating shaft 161 through a pin structure. The first transmission member 140 is located between the first connecting member 124 and the second connecting member 123, and the first connecting member 124 and the second connecting member 123 are perpendicular to the rotating shaft 161.
[0049] In some other embodiments, the driving mechanism further includes a second transmission member 163 and a third transmission member 164. The second transmission member 163 is arranged at the docking end 141. The third transmission member 164 is meshed and connected with the second transmission member 163. The third transmission member 164 can perform reciprocating rotation or reciprocating linear motion.
[0050] Further, the driving mechanism further includes a driving member 130. The driving member 130 is connected to the third transmission member 164, and the third transmission member 164 is driven by the driving member 130 to perform reciprocating rotation or reciprocating linear motion.
[0051] In some specific embodiments, when both the second transmission member 163 and the third transmission member 164 are gears, the teeth of the second transmission member 163 are meshed and connected with the teeth of the third transmission member 164. The driving member 130 has a rotatable connection end, and the third transmission member 164 is fixed to the connection end. The driving member 130 drives the third transmission member 164 to rotate reciprocally, so that the docking end 141 can be driven to rotate reciprocally under the transmission of the second transmission member 163, enabling the first mounting member 120 to swing. In this embodiment, the driving member 130 is a motor.
[0052] In some specific embodiments, the second transmission member 163 can be a worm gear, and the third transmission member 164 can be a worm. The teeth of the second transmission member 163 are meshed and connected with the teeth of the third transmission member 164. The driving member 130 has a rotatable connection end, and the third transmission member 164 is fixed to the connection end. The driving member 130 drives the third transmission member 164 to rotate reciprocally, so that the docking end 141 can be driven to rotate reciprocally under the transmission of the second transmission member 163, enabling the first mounting member 120 to swing. In this embodiment, the driving member 130 is a motor.
[0053] In some specific embodiments, the second transmission member 163 can be a gear, and the third transmission member 164 can be a rack. The teeth of the second transmission member 163 are meshed and connected with the teeth of the third transmission member 164. The driving member 130 has a connection end capable of linear motion, and the third transmission member 164 is fixed to the connection end. The driving member 130 drives the third transmission member 164 to perform reciprocating linear motion, so that the docking end 141 can be driven to rotate reciprocally under the transmission of the second transmission member 163, enabling the first mounting member 120 to swing. In this embodiment, the driving member 130 is an electric push rod or a cylinder.
[0054] Such as Figure 7 and Figure 8 In an embodiment shown in the present application, the third transmission member 164 is a synchronous belt, and the second transmission member 163 is a synchronous pulley. The teeth of the second transmission member 163 are meshed and connected with the teeth of the third transmission member 164. The driving member 130 has a rotatable connection end, and the third transmission member 164 is connected to the connection end of the driving member 130 through a driving synchronous pulley 165. The driving member 130 drives the third transmission member 164 to rotate reciprocally, so that the docking end 141 can be driven to rotate reciprocally under the transmission of the second transmission member 163, enabling the first mounting member 120 to swing. In this embodiment, the driving member 130 is a motor.
[0055] In some specific embodiments, the setting direction of the synchronous belt is perpendicular to the setting direction of the rotating shaft 161, and the setting direction of the motor is parallel to the setting direction of the rotating shaft 161.
[0056] Further, the synchronous pulley is rotationally connected to the rotating shaft 161, and the docking end 141 is fixedly connected to the synchronous pulley. Therefore, when the first transmission member 140 is disconnected from the docking end 141, the position of the docking end 141 in the radial direction relative to the rotating shaft 161 remains unchanged, facilitating the subsequent electromagnetic suction connection between the docking end 141 and the first transmission member 140. It also facilitates the coaxial transmission of force.
[0057] Further, the docking end 141 and the synchronous pulley are connected by a diameter-changing block 162. One end with a larger diameter of the diameter-changing block 162 is fixedly connected to the docking end 141 by bolts, and one end with a smaller diameter of the diameter-changing block 162 is fixedly connected to the synchronous pulley by bolts.
[0058] Further, the rotating structure further includes a mounting seat 170. Support portions 171 are symmetrically arranged on both sides of the mounting seat 170. The rotating shaft 161 is rotatably arranged on the support portions 171, and the driving member 130 is fixed to the mounting seat 170.
[0059] In some specific embodiments, the mounting seat 170 is a metal plate member. The support portions 171 are formed on both sides of the metal plate member by bending. The support portions 171 may be provided with bearing seats for the rotating shaft 161 to be rotatably arranged on the support portions 171. The metal plate member is also provided with a support plate for mounting the driving member 130.
[0060] Further, the driving mechanism further includes an adjusting structure. The adjusting structure is arranged on the mounting seat 170 and is used to adjust the tension of the synchronous belt. Specifically, the adjusting structure includes an adjusting block 181. The adjusting block 181 can move closer to the straight section of the synchronous belt (that is, the part of the synchronous belt sleeved between the two synchronous pulleys is called the straight section), so that the straight section on one side of the synchronous belt moves towards the straight section on the other side, thereby adjusting the tension of the synchronous belt.
[0061] In some specific embodiments, the movement adjustment of the adjusting block 181 is realized by an adjusting member 182. The adjusting member 182 is threadedly connected to the mounting seat 170, and the end of the adjusting member 182 presses against the adjusting block 181, so that a part of the adjusting block 181 fits the straight section of the synchronous belt. Among them, the part of the adjusting block 181 that fits the straight section is an inclined surface parallel to the straight section. The setting of the inclined surface can effectively extend the service life of the synchronous belt.
[0062] Further, the mounting seat 170 is provided with a protrusion for the adjusting member 182 to be threadedly connected. The adjusting member 182 can be selected as a bolt.
[0063] In some embodiments, the electric swing frame 100 of the present application further includes a sensing device for detecting changes in the swing position of the first mounting member 120. In some specific embodiments, the sensing device is an angle sensor that senses the change in the swing angle of the first mounting member 120 so that the controller can adjust the operation of the driving member 130 according to the information collected by the angle sensor.
[0064] When manual swinging is required, the motor is disabled, and the first transmission member 140 remains disengaged from the docking end 141. At this time, the docking end 141 and the second transmission member 163 remain stationary, and the first transmission member 140 rotates forward and backward following the reciprocating swing of the first mounting member 120.
[0065] When the electric swing mode is turned on, the angle sensor continuously detects the current offset angle of the first mounting member 120. When it is detected that the angle does not change within a preset time period, it indicates that the first mounting member 120 is in a stationary state. Immediately, the first transmission member 140 and the docking end 141 are electromagnetically attracted and locked, and the motor rotates forward and backward at a preset speed and cycle, and the motor follows the oscillation waveform.
[0066] When the angle sensor detects a change in the swing angle of the first mounting member 120 within a certain period of time, it indicates that it is in a swinging state. When the first mounting member 120 swings from Figure 6 the swinging position through Figure 3 and Figure 4 the neutral position shown, the controller calculates the angular velocity and angular acceleration of the first mounting member 120 in a certain period of time before reaching the neutral position, and electromagnetically attracts and locks at the moment of reaching the neutral position. The motor matches the motor speed according to the angular velocity value, and then fine-tunes the motor speed to achieve the preset swing speed and amplitude. In case of manual intervention in the swing, the electromagnetic clutch automatically disengages and the motor is immediately disabled.
[0067] Due to the presence of the angle sensor, the controller analyzes the swing position of the first mounting member 120 based on the angle change before the motor intervenes, making the motor intervention process more seamless. At the same time, the direct drive of the motor can also achieve adjustable swing speed and swing amplitude.
[0068] In some other embodiments, the electric swing frame 100 further includes a second mounting member 110. The rotating mechanism is disposed on the second mounting member 110, and the end of the first mounting member 120 away from the rotation center is connected to the second mounting member 110 through a link structure to limit the swing amplitude of the first mounting member 120.
[0069] In some specific embodiments, as Figure 9 shown, the rotation center of the first mounting member 120 is at the middle position, and both ends of the first mounting member 120 are connected to the second mounting member 110 through link structures, thereby being able to limit the swing amplitude of the ends of the first mounting member 120.
[0070] In some specific embodiments, the first mounting member 120 includes at least two third connecting members 122 and at least one fourth connecting member 121. The third connecting members 122 and the fourth connecting member 121 are lap-connected to form the first mounting member 120.
[0071] In the embodiments shown in the embodiments of the present application, two third connecting members 122 are provided, and one fourth connecting member 121 is provided. The fourth connecting member 121 is disposed between the two third connecting members 122, and the two fourth connecting members 121 are respectively fixed to the two ends of the third connecting member 122. The two fourth connecting members 121 are arranged in parallel, and the third connecting member 122 is perpendicular to the fourth connecting member 121. Among them, the first connecting member 124 and the second connecting member 123 are disposed at the middle position of the bottom of the fourth connecting member 121. The setting direction of the fourth connecting member 121 is parallel to the axial direction of the rotating shaft 161. Both ends of the two third connecting members 122 are connected to the second mounting member 110 through a link structure, making the whole structure more stable.
[0072] Among them, the link structure includes a first link 151 and a second link 152. The first link 151 is hinged to the second link 152, and the first link 151 and the second link 152 are respectively hinged to the second mounting member 110 and the first mounting member 120.
[0073] Further, as Figure 11 shown, the third connecting member 122 has a first plate 1222 and a second plate 1221 that are perpendicularly connected to each other, so that the third connecting member 122 is in an L shape. The two third connecting members 122 are symmetrically arranged. The angle formed by the first plate 1222 and the second plate 1221 of one third connecting member 122 faces the other third connecting member 122, so that the two third connecting members 122 form a limiting frame to facilitate the quick positioning and installation of the seat body 200.
[0074] Among them, the link structure is hinged to the first plate 1222, and the second plate 1221 is fixedly connected to the fourth connecting member 121 by bolts or welding.
[0075] In some other embodiments, as Figure 10 shown, the second mounting member 110 includes a plate-like member 111, and connecting plates 112 are bent on both sides of the plate member. The link structure is hinged to the connecting plates 112. Further, a limiting post 113 for restricting the swinging amplitude of the link structure is provided on the connecting plates 112.
[0076] The embodiments of the present application have been described in detail above with reference to the drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
